Garbage or trash is a major kind of environmental pollution.Each person produces about 2kg of trash a day.We are making waste products faster than nature can break them down.And we are using up resources（资源）faster than they can be replaced（取代）.

    This adds up to trouble for the environment.Where does all that garbage go?What can be done to help dispose of（处理）garbage?How call we make less garbage?

    Garbage isn't just the smelly rotting fruits,vegetables or meat that we throw away in our homes.Those are only a small pan of all the stuff we throw away.We create other kinds of waste,in construction,mining and in our factories.

    Did you ever wonder what happens to your garbage?Most is burned or buried in landfills（垃圾填埋场）Less than a quarter of our waste is recycled.

    With a population of 1.3 billion（十亿）,garbage is a big problem for China.Chinese cities create around 148 million tons of garbage every year.The amount is growing at around 10 percent each year.

    Once we used about 3 billion plastic shopping bags every day in China.The result was a great waste of resources and serious pollution.So we did something about that.Now we use more cloth bags and shopping baskets when we shop.

    In the coming years China will build waste-to-energy plants in cities to clean up the garbage.But there's a lot more that needs to be done.And you can play a part.

    You don't need to travel far away to write a travel diary.Your writing can start with a family vacation or a weekend get away.All you need is a destination or a place of departure（出发）!

    {#blank#}1{#/blank#}Your trip journal can begin before your trip has started.Use your journal to start planning the things you want to do.It can be a cool restaurant where you want to eat,a hike you want to go on or different sights you want to see.

With the clicking of walking sticks and determined steps, a long line of walking group along the winding road is a fantastic sight. Almost each of the walkers is using some kind of fitness tracker. A few Fitbits, some Xiaomi wrist bands (手环), a couple of phone apps and some other pedometers (计步器) — and all, they say, are counting their steps.

    Fitness trackers are in. Sales figures for 2016 released by Internet Data Center (IDC) indicated 25% market growth compared to the previous year, with Fitbit taking the lion's share, followed by the brand Xiaomi.

    However, the wearables market has had a rollercoaster ride in recent months. Jawbone, once a popular fitness tracker brand, announced that it is leaving the consumer market. Microsoft has removed its Fitness Band on its online store although it is still available on retail (零售) giant Amazon. Fitbit remains a key brand name at the heart of the fitness tracker revolution. But it is recently reported to be cutting down on workers, and its founder James Park said it experienced “softer than expected” sales recently.

    Counting steps is probably the most common use of wearable devices (可穿戴设备), but recently experts have questioned whether the golden goal of walking 10,000 steps a day is actually worthwhile, and a US study concluded that health trackers did not aid weight loss.

Analyst Ben Wood from CCS Insight used to wear a fitness tracker on either wrist. Now, however, his concern is about users'experience — these devices don't tell you anything new after a while. There are also battery problems and many of the older and cheaper varieties aren't waterproof (防水的).

    It is estimated that more than half the world's population is bilingual (双语的), and in an increasingly globalised world, there are obvious benefits of speaking more than one language. However, for many years, parents were advised not to teach their children to speak more than one language from birth. Learning two or more languages simultaneously (同时) was believed to cause confusion and slow down academic development. While it is certainly true that children who are learning to speak more than one language as their mother tongue will often mix the languages up or speak a little later, these are temporary problems, and there is no reason to avoid teaching a child more than one language.

    In fact, there are plenty of reasons to encourage your child to become bilingual from birth. As well as the obvious benefits of being able to communicate with more people, and the possibility of earning more money, children who speak more than one language have been shown to score more highly in achievement tests at school. This is true for mathematics as well as tests of verbal (言语的) skills.

    And in later life it has been found that bilinguals, on average, will tend to develop Alzheimer's disease five years later than monolingual speakers. Speaking three or more languages offers even more protection. It seems that the increased number of connections within the brain allows bilinguals to cope better with brain damage.

    But is it too late if you haven't already learned a second language in childhood? It used to be thought that the adult brain was very fixed, but recent research has shown that we continue to develop new connections in the brain throughout our lives, meaning that it's perfectly possible to learn another language to a high standard. Older learners are less likely to have native-like pronunciation, but they are better at learning vocabulary as they are able to use far more skills and strategies than children. And learning a language is like using a muscle – the more you use it, the stronger it gets, meaning that you will find your third language easier than your second, and so on.

    Making decisions when shopping is often tough. Even if you're satisfied with the first dress you try on, would you go on looking for alternatives, comparing styles and prices, until you drop dead?

    According to a recent Wall Street Journal column, psychology researchers have studied how people make decisions and concluded there are two basic styles.“Maximizers” are people who want the best. They like to take their time and weigh a wide range of options—sometimes every possible one—before choosing.“Satisfiers” would rather be fast than thorough. They are people who want to be good enough.

    Schwartz and his colleagues followed 548 job-seeking college seniors at 11 schools from October through their graduation in June. They found that the maximizers landed better jobs. Their starting salaries were, on average, 20 percent higher than those of the satisfiers, but they felt worse about their jobs.

    There is no right choice.“The maximizer is kicking himself because he can't examine every option and at some point had to just pick something,” Schwartz says.“Maximizers make good decisions and end up feeling bad about them. Satisfiers make good decisions and end up feeling good. ”

    Faced with so many choices in our lives, we need to learn how not to waste time and energy on our decision-making, says Jane C. Hu in Slate online magazine.Hu suggests, decrease your range of options. Once you've arrived at a decision, stick with it. Just accept that no decision is ever completely perfect, and remind yourself that it is the best you can do at the moment.

When it comes to having fun in the sun, it's easy to lose track of time. If you're not careful, this can be quite dangerous.{#blank#}1{#/blank#}But it can easily be prevented—all you need is a little sunscreen.

{#blank#}2{#/blank#}People have been using chemical pastes to protect themselves from the sun for centuries. But the first modern sunscreen sold on the market was offered by French company: L'oreal in 1935.

Several other companies were quick to release their own sunscreens. Perhaps the biggest advancement in the world of sunscreen came in the 1970s, when scientists started looking at the sun protection factor, or SPF.{#blank#}3{#/blank#}
